What is the work function of a certain metal if a strong beam of light can cause a breakaway of electron from its surface? [h = 6.63 × 10\(^{−34}\) Js, f\(_0\) = 5.3 × 10\(^{13}\) Hz]

An electron of mass, m, and charge, e moves through the electric field of potential difference V\(_o\) with a speed, v. Show that de Broglie wavelength associated with the electron is given as \(\lambda\) = \(\frac{\text{h}}{\sqrt{2meV_o}}\), where h is the Plank's constant.

A body of mass, M, moving with velocity, V, has a wavelength, X, associated with it. This phenomenon is called----------

Which of the following phenomena supports the theory that waves have a particle nature?
